Abstract
A method and apparatus for an electronic device 101 operating in a piconet 100 to assign itself a unique identifier 112 is provided. Once the device 101 assigns itself the unique identifier 112, which may be temporary in nature, the device 101 may use the temporary identifier 112 to identify itself to other devices 102-105 operating within the piconet 100, which may be a Bluetooth local area network. In accordance with one embodiment of the method, a device 101 may first scan the piconet 100 to determine device identifiers 113-116 corresponding to devices 102-105 that are operating within the piconet 100. After scanning the device 101 stores the device identifiers 113-116 in a list and queries the list to determine which identifiers are included in the list. The device 101 then selects the temporary, unique identifier 112 that is not found in the list. The unique identifier 112 may then be used to identify the device 101 to the piconet.
